my ipod was at 20% last night. so i plugged it in before i went to bed. woke up this morning, and it's still at 20%, but the symbol over the battery is displaying the plugged in icon. which is usually meant when the battery is 100% and plugged in. so i unplugged it, and plugged it back in. it displayed the lightning icon to show it was charging. but then after a couple seconds, it went to the plugged in icon again. my ipod is now at displaying 10% but i don't know if that's right or not. ps, i can see and sync my ipod in itunes still. also tried turning it off and turning it on, didn't update the battery. tried restarting my PC too.
